Schistosomiasis, an important parasitic disease, is severely harmful to human heath in China . The beach along the Yangtze River is a important habitat of snail that is Schistosomiasis's only intermediate host. program of afforesting for wiping out snail(Oncomelania hupensisi) and Schistosomiasis, comprehensive administration and exploitation of the three kinds of beaches proposed by Peng Zhenhna and Jiang Zehui is a pioneering.work hased on the ecological and economic theory. The development process of forestry for snail control and Schistosomiasis prevention is reviewed, and mechanisms and major afforesting techniques are summarized in this paper. 展开更多
